Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A measuring tool for measuring the center height of a V-belt pulley, comprising a measuring gauge 1, an angle measuring head 16 and a workpiece positioning block 14. The measuring meter 1 is fixed on the guide post 7 through the measuring meter fixing plate 2 . Specifically, the measuring gauge 1 is passed through the measuring gauge fixing plate 2 , and the screws pass through the measuring gauge fixing plate 2 and fix the measuring gauge fixing plate 2 on the top of the guide post 7 .

The guide post 7 is erected, and a guide sleeve 17 is pierced thereon. The side lugs of the guide sleeve 17 are located below the measuring gauge 1 . The angle measuring head fixing plate 4 is fixed on the guide sleeve 17 . An angle measuring head 16 is fixed on the angle measuring head fixing plate 4 . The height change of the angle measuring head 16 is transmitted to the measuring table 1 by the guide sleeve 17 .

The lower part of the guide post 7 is inserted into the handle fixing plate 9 . Specifically, the guide post 7 is inserted into the small round hole of the handle fixing plate 9, a large round hole with a coaxial center is arranged below the small round hole, and a small circular plate 18 is embedded in the large circular hole, and the screw passes through the small circular plate. 18 and threaded on the guide post 7. Turn this screw and can fine-tune the height of guide post 7.

A small linear guide rail 10 is arranged below the handle fixing plate 9 , and the handle fixing plate 9 and the small linear guide rail 10 are slidably connected. The small linear guide rail 10 is fixed on the base 11 . The small linear guide rail 10 connects the handle fixing plate 9 and the base 11. A handle 6 is provided on the handle fixing plate 9 . When the handle 6 is pulled, the handle fixing plate 9 slides on the small linear guide rail 10 to adjust the horizontal distance from the angle measuring head 16 to the workpiece 15 .

The fixing plate 4 of the angle measuring head is screwed with a limit bolt 3 . The limit bolt 3 passes through the angle measuring head fixing plate 4 and the nut 8 and is screwed to the handle fixing plate 9 . The limit bolt 3 is covered with a spring 5 , the upper end of the spring 5 touches the angle measuring head fixing plate 4 , and the lower end touches the handle fixing plate 9 . The spring 5 is used to support and balance the measuring device.
